In use for 2 months and wifi and temperature cooling worked fine. Start it up 2 hrs before bedtime in COOL Mode and than switch to ECO before sleep (quieter).
I usually can bring a 77-80 degree bedroom down to 68 in 2-3 hours.  On cooler nights I use a window fan and not the A/C fan.
I found out that my Frigidaire remote from a number of years old 6000 BTU worked on the newer 8000 model
